Copper tape for transformer installation
Tin-free bronze is also called Wuxi bronze, which generally has high corrosion resistance, outstanding lubricity, high electrical conductivity, and also has outstanding mechanical properties. These alloys are also called special bronzes. Special bronze can be used to manufacture mechanical parts and so on. Tin bronze (tin phosphor bronze) is an alloy Copper tape for transformer installation that has been used in my country for a long time..
Bronze is an alloy of copper and tin, and the tin content is about 5% to 10%. Used to cast bearings, pump housings, valves, gears. Sometimes it also refers to a binary or multiple alloy composed of copper and aluminum, silicon, beryllium, and manganese. This alloy has good castability and high corrosion resistance.Free-cutting phosphor bronze is Bronze is a large variety, including phosphor bronze and phosphor bronze. It has strong chemical stability in sea water, dilute sulfuric acid, solution, and very dilute sodium carbonate solution
It is suitable for alloys that have a quenching effect after heat production and cooling, such as 6063. T5: After hot production, it is quenched and then artificially aged. Products made without a specific chain degree, such as kneaded, hot-rolled, and cast products. This quenching and tempering is suitable for alloys that have a quenching effect after cooling after hot production, such as 6063. T4: Natural aging treatment after solution treatment.
The process of these treatments is called conditioning, and the result of conditioning is the degree of chain.Heat treatment of aluminum alloy 1. Its intention is to improve the resistance to hard corrosion cracking and avoid deformation during quenching. H112 does not deliberately manipulate the production of hardened products, but the mechanical properties must be ensured. If higher strength is not ensured, it can also be regarded as T6 chain degree.

After being hardened, its tensile strength and hardness increase, while plasticity decreases. The first is to improve the tensile strength and improve the technical code for 'H + the symbol of the main element (except zinc) + the mass fraction of copper + the mass fraction of the main element + the mass fraction of other elements'. Nickel content is generally 10%, 15%, 20%, the higher the content, the whiter the color. commonly used are Qsn43 Qsn6. A.is an alloy of copper and nickel. Cast brass. 2) Special bronzes join other elements to replace tin, or Wuxi bronzes.
The casting shape is messy. For example, Qal7 indicates that the aluminum content is 5%, and the other aluminum bronze ZQsn101 that is copper indicates that the tin content is 10%. It is suitable for castings with messy shapes but low density requirements, such as sliding bearings, gears, etc.
They are satisfied with various corrosion resistance and special electrical and thermal functions. Industrial copper-nickel alloys can be divided into structural copper-nickel alloys and electrical copper-nickel alloys according to their functional characteristics and application ranges. Most special bronzes have higher mechanical properties, wear resistance and corrosion resistance than tin bronzes. H68 and H59 belong to dual-phase brass, which are widely used in structural parts of electrical appliances, such as bolts, nuts, washers, tension springs, etc. For cast products, add the word 'Z' before the code. When the tin content is greater than 10%, it is suitable for casting.
Red copper is China copper tubes company with a high copper content, and the total content of other impurities is below 1%. In addition to brass and white copper, other copper alloys are collectively called bronze. Casting tin bronze is directly sold as ingots, and cast into castings by the foundry. Since a and are near the electrode potential, and the tin in the composition produces a fine tin dioxide film after nitriding, the corrosion resistance of the atmosphere and seawater is increased, but the acid resistance is only poor. Pure copper and nickel can significantly improve strength, corrosion resistance, electrical resistance and thermoelectricity
